New Revision: 338055
URL: https://svnweb.freebsd.org/changeset/base/338055

Log:
  Remove some vestiges of IPI_LAZYPMAP on i386.
  
  The support for lazy pmap invalidations on i386 was removed in r281707.
  This removes the constant for the IPI and stops accounting for it when
  sizing the interrupt count arrays.
